Former Olympic gymnast Shannon Miller has announced that she and husband John Falconetti are expecting their second child.

The pregnancy comes as a surprise, since the 35-year-old just overcame a battle against ovarian cancer two years ago.

A 7-time Olympic gold medalist, Miller announced the miraculous pregnancy on her website Monday.

"Things were going fantastic with the launch of my company, Shannon Miller Lifestyle, my foundation was growing and we hoped our family would expand as well," explained Miller on ShannonMillerLifestyle.com. "Then my world stopped. Instead of calling my parents to tell them they had another grandchild on the way, I was calling to tell them I may have cancer. Our baby plans were put in hold indefinitely."

In 2011, Miller underwent surgery to remove a germ cell tumor, a rare form of ovarian cancer.

Furthermore, Miller's left tube and ovary were removed, and the athlete underwent intense chemotherapy treatments. She and her husband worried that they would never be able to welcome siblings for their son Rocco, born in 2009.
